    Yes... I did get the Filter running just fine. I was passing the
    binary image as the initial level set initially... which was wrong
    on my part. The initial level set has to be a distance map. Which
    can be generated using SignedDenxxxDistanceMapImage filters as
    described in previous replies. Moreover if your result for
    FASTMARCHINFILTER is black image ... it basically hints that you
    have no initial level set. Check the code before
    FastMarchImagingfilter to make sure you have at least some binary
    image at that point.<br>
    <br>
    More details would help us in guiding you.<br>

                          Hi Vimal,<br>
                          <br>
                          Did u manage to use the
                          GeodesicAcctiveContourImageFilter in the end?<br>
                          I am facing a similar problem. I can see the
                          output of all the filters, except the output
                          of the FastMarchingFilter which is just a
                          black image. <br>
                          I would really appreciate any suggestions
                          about why this happens. I tried to look at
                          older posts aswell, but there was no further
                          information or solution to this problem.<br>
                          Thanks a lot,<br>
